Open well and establishing method thereof

Abstract

The invention relates to the technical field of automatic supply of ground water level in soil, in particular to an open well and an establishing method thereof. The open well comprises a well body, the interior of which is provided with a steel bar framework of the well body. The height of the steel bar framework of the well body is the same as the depth of the well body. The framework is wrapped by a metal wire net and anti-filter geotechnical cloth. The open well and the establishing method thereof have the following beneficial effects: the side wall of the well body is permeable to water; the water permeable area is increased by a dozen of times than an ordinary water well; after water is fetched, the underground water level can permeate from the side wall so that rapid recovery and supplement are obtained; resources, capital and manpower can be saved; during construction, hole-wall collapsing danger is avoided and construction speed is high; sand stones of the side wall of the well body are effectively prevented from falling into the well body; there is no need to desilt and clear sand for a long time; the construction cost is low; the water percolating capacity is high; a conventional large number of machine wells are replaced; and the establishing method helps improve the ecological environment and restores the underground water level; the initiative of farmers to open up the open well for fetching water is improved; once people fall into water, they can climb along the framework; and the open well is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of underground water level replenishment, in particular to an open well and a construction method thereof. Background technique [0002] In some relatively water-scarce areas, due to the long-term dependence on pumped wells to pump a large amount of groundwater for irrigation, the groundwater level in the area has seriously dropped, and rivers and lakes have dried up. [0003] Due to the uneven precipitation in the area and the rapid loss of rainwater on the surface along the rivers and gullies, it is difficult to replenish groundwater in a timely and effective manner. In the long run, the ecological environment is often destroyed, seriously affecting the local economic development and living environment. [0004] In view of the above situation, excavation of seepage wells is usually used to replenish groundwater. Patent application document CN103835333A discloses a method for repairing deep underground seep...

AI Technical Summary

Problems solved by technology

Although the above-mentioned inspection well has improved its own strength to a certain extent, it is not suitable for seepage wells, and the structure of this kind of well is relatively complicated. It is extremely difficult to apply to seepage wells whose depth is several times the depth of the inspection well to supply groundwater. The construction cost is also very high, and no inspiration can be obtained from it, so as to solve the problems that the well wall of ordinary seepage wells is easy to collapse in reality, and the sand and soil on the well wall naturally fall off in the later period of use
